1. Patent 1,529,461, to Brogden and Trowbridge, claiming a new
and improved process of preparing fresh fruit for market by
subjecting it to the action of a solution of borax, and thus,
through the fungicidal properties of that chemical, rendering it
resistant to the decay caused by blue mold, and also claiming, as a
product, fresh citrus fruit of which the rind carries borax of
small amount, but sufficient to render the fruit resistant to such
decay, is invalid because the process was anticipated and the
product is not within the patent law. Pp.

MR. JUSTICE McREYNOLDS delivered the opinion of the Court.
The Brogdex Company, present owner of United States letters
patent No. 1,529,461, relating to "certain new and useful
improvements in the art of preparing fresh fruit for market,"
applied for August 13, 1923, and issued to Brogden and Trowbridge
March 10, 1925, presented its bill of complaint to the District
Court for Delaware April 15, 1926, wherein it charged that the
defendant (petitioner
Page 283 U. S. 6
here), the American Fruit Growers, Inc., had infringed and asked
an injunction, accounting, damages, etc. It relied upon Claims Nos.
1, 2, 3, 4, 5, 6, 7, 9, 14, 15, 16, 17, and 18, which describe the
process of treatment, also Nos. 23, 24, 25, and 26, which concern
the product.
Both courts below held all of these claims valid and infringed,
and directed that petitioner be enjoined from using any process
therein specified, also from manufacturing, selling, or using
"treated fruit embodying and containing the invention described in
said letters patent and secured by any of said [product]
claims."
Of the process claims, the following is characteristic:
"3. In the preparation of fresh fruit for market, the process
which comprises subjecting fruit to the action of an aqueous
solution of borax, the fluidity, strength and temperature of the
treating solution, and the duration of the treatment, being such
that exposed rind or skin tissues of the fruit are effectively
impregnated with borax and rendered resistant to blue mold decay,
while at the same time the fruit is not scalded nor is its
freshness or edibility otherwise substantially impaired."
The following is typical of the product claims:
"26. Fresh citrus fruit of which the rind or skin carries borax
in amount that is very small but sufficient to render the fruit
resistant to blue mold decay."
"The claim of a patent must always be explained by and read in
connection with the specification."
Carnegie Steel Co. v.
Cambria Iron Co., 185 U. S. 403,
185 U. S.
432.
The specification in respect of the patent states:
"This invention relates to art of preparing fresh fruit for
market, and in particular it relates to processes for the treatment
of citrus and other fruits in such manner that the development of
molds and the like upon the fruit, and especially the development
of blue mold and infection by blue mold spores, is prevented or
arrested either wholly or to such large extent as greatly to
prolong
Page 283 U. S. 7
the marketable life of the fruit beyond what has been possible
heretofore; the complete treatment most desirably also including a
step of providing the fruit with a very thin film-like coating of
protective material comprising a waxy substance such as paraffin,
all as will more fully hereinafter appear."
"The greatest present utility of the invention is in the
treatment of citrus fruits such as oranges, grapefruit, lemons,
tangerines, etc.; also apples and other fruits that are attacked by
blue mold or the like. The invention is broad, however, and the
term fruit as herein employed is to be understood as not
necessarily restricted to fruit in the sense in which the word is
usually employed, but is to be understood broadly as including not
only fruit proper, but also vegetables, such as tomatoes or the
like, that can be treated to advantage in accordance with the
principles of the invention to be hereinafter set forth."
"For the sake of a concrete example whereby the principles of
the invention may be illustrated and explained, reference will be
made hereinafter more particularly to the treatment of citrus
fruit, especially oranges and lemons, which are especially subject
to attack and destruction by blue mold. It is a well known fact
that a large part of the losses from decay in the marketing of
various fruits, such as citrus fruits and apples is attributable
directly to the action of blue mold. The problem of how to suppress
or control blue mold development on fruits has been the subject of
extensive and careful investigation, but admittedly no thoroughly
satisfactory solution of the problem has heretofore been offered.
In spite of elaborate precautions taken in the handling and
transportation of fruits to market, it is not uncommon for
shipments of oranges and the like to arrive at marketing points
showing in some cases as much as 30 to 40 percent decay directly
attributable to blue mold. The various investigations of the
subject have shown that, while blue mold
Page 283 U. S. 8
does not ordinarily attack perfectly sound fruit that is free
from bruises, cuts, thorn-pricks or punctures, the slightest
surface cut or scratch affords a point of attack by providing
lodgment for blue mold spores, which develop with great rapidity
and soon bring about complete destruction of the infected fruit. .
. ."
"The present applicants have discovered that, by proper
treatment of the fruit in the packing house, it is possible to
greatly reduce, and often to absolutely prevent, the growth or
development of blue mold on fruit for long periods of time, and
thus to materially lessen or even eliminate the heretofore
unavoidable losses from decay. Moreover, it is possible to achieve
these results without upsetting or greatly changing present
practice so far as concerns the mechanical handling of fruit in
packing houses of the modern type. Thorough practical tests of the
novel processes have demonstrated conclusively that, by proceeding
in accordance with the invention, blue mold development can be
arrested and fruit can be rendered immune to attack by blue mold
spores in a simple and effective manner without affecting the
freshness and flavor of the fruit, the marketable life of the fruit
being thus prolonged far beyond that of untreated fruit. In view of
the well known persistent activity of blue mold spores even under
conditions fatal to the parent mold, the importance of this
achievement is obvious. In general, the process of the invention
involves applying to the fruit a mold-inhibiting reagent comprising
the boric acid radical, said compound being most desirably alkaline
in reaction and being employed in concentration effective to render
the surface of the fruit unfavorable as a medium for blue mold
development. Ordinary borax (Na1B4O7+1OH2O) has been found, after
extensive investigation, to be especially potent in its retarding
and inhibiting action in this connection, and this substance is
considered at present to be the most desirable to employ
Page 283 U. S. 9
in practicing the invention. A water solution of borax is
alkaline in reaction, but is without corrosive or other
deteriorating action upon fruit to which it is applied. Boric acid
is not so effective as a mold-retarder as is borax, but compounds
of boron, whether acid or alkaline, appear to have a specific
inhibiting action upon blue mold, and hence it is not desired to
limit the invention, so far as concerns compounds of boron, to the
employment of an alkaline treating solution."
"The method of applying the treating solution to the fruit may
assume various specifically different forms, the precise details of
procedure being not essential to the invention in its broader
aspects. However, where it is desirable, as may often be the case,
to carry out the process without changing prior practice any more
than is strictly necessary, the application of the mold-retarding
agent may be effected as a part of or in conjunction with the usual
washing operation to which the fruit is initially subjected in its
handling according to modern packing house methods, especially as
most of the mold-retarding agents herein contemplated also have
excellent cleansing or detergent properties. Accordingly, in the
practice of the invention, the mold-retarding agent, borax in a
specific instance, may be added in proper mold-inhibiting quantity
directly to the wash water in the usual soaking tank into which the
fruit is dumped from the field boxes as it comes from the groves. .
. ."
"From this point on, the handling of the fruit in further
preparation for boxing and shipment may or may not involve
additional preservative treatment in accordance with the principles
of the invention. This depends upon whether or not the fruit is to
receive an application of protective coating material for the
purpose of preventing or reducing shrinkage and withering and of
ensuring conservation of the original freshness and flavor of the
fruit for prolonged periods of time. Generally this further
Page 283 U. S. 10
treatment is highly desirable, and if the benefits of the
invention are to be realized to the fullest extent, this further
treatment should be carried out. It consists in applying to the
fruit a normally solid protective material, especially paraffin or
like waxy material, in such condition that it can be spread all
over the surface of the fruit to produce an extremely thin
protective film which is not noticeable except by the expert eye
and does not interfere with the so-called breathing or
transpiration of the fruit to an undesirable extent, but which is
effective to conserve the original plumpness and freshness of the
fruit as above stated. . . ."
"In the foregoing disclosure of the principles of the invention,
reference has been made more particularly to blue mold as a source
or cause of decay. Such reference to blue mold is to be taken not
as restrictive, but as generic and as intended, both in the
specification and in the claims, to cover not only blue mold but
all kindred rot and decay organisms and diseases generally amenable
to treatment in accordance with the invention, to which fruit is or
may be susceptible and by which it may be damaged under the
conditions prevailing in packing and marketing. . . ."
Petitioner admits ownership of plants which pack and sell citrus
fruits, and that, when preparing these for market, it caused them
to be dipped in a borax solution in order to prevent or retard
decay incident to growth of blue mold. Under the treatment applied,
the raw fruit is immersed in a cold or warm solution of borax or
boric acid, permitted to remain until thoroughly wet, then rinsed,
dryed, and brushed. Infringement is admitted, if the patent is
valid.
In defense, petitioner maintains that the product claims of the
patent fail to describe an article of manufacture within the
meaning of the statute. Also that the process
Page 283 U. S. 11
claims are invalid for various reasons, among them anticipation
by United States letters patent No. 683,899, issued October 8,
1901, upon application of Simeon Bishop.
Is an orange, the rind of which has become impregnated with
borax, through immersion in a solution, and thereby rendered
resistant to blue mold decay, a "manufacture," or manufactured
article, within the meaning of § 31, title 35, U.S.Code?
"Any person who has invented or discovered any new and useful
art, machine, manufacture, or composition of matter or any new and
useful improvements thereof, not known or used by others in this
country, before his invention or discovery thereof, and not
patented . . . may . . . obtain a patent therefor."
Answering affirmatively, the circuit court of appeals said:
"The product claims define an article of manufacture, since the
fruit is the result of a process which is defined and described,
and not a natural product. The product is a combination of the
natural fruit and a boric compound carried by the rind or skin in
an amount sufficient to render the fruit resistant to decay. The
complete article is not found in nature, and is thus an article of
manufacture.
Riter-Conley Mfg. Co. v. Aiken et al., 203 F.
699."
This position, we think, is not tenable.
"Manufacture," as well defined by the Century Dictionary, is
"the production of articles for use from raw or prepared
materials by giving to these materials new forms, qualities,
properties, or combinations, whether by hand labor or by
machinery;"
also "anything made for use from raw or prepared materials."
Addition of borax to the rind of natural fruit does not produce
from the raw material an article for use which possesses a new or
distinctive form, quality, or property. The added substance only
protects the natural article
Page 283 U. S. 12
against deterioration by inhibiting development of extraneous
spores upon the rind. There is no change in the name, appearance,
or general character of the fruit. It remains a fresh orange, fit
only for the same beneficial uses as theretofore.
In
Hartranft v. Wiegmann, 121 U.
S. 609,
121 U. S. 613,
this Court considered the meaning of the words "manufactures of
shells," and held that "cleaning off the outer layer of the shell
by acid, and then grinding off the second layer by an emery wheel,
so as to expose the brilliant inner layer," did not convert it into
a manufacture.
"The shells in question here were not manufactured, and were not
manufactures of shells, within the sense of the statute imposing a
duty of 35 percentum upon such manufactures, but were shells not
manufactured, and fell under that designation in the free list.
They were still shells. They had not been manufactured into a new
and different article, having a distinctive name, character, or use
from that of a shell. The application of labor to an article,
either by hand or by mechanism, does not make the article
necessarily a manufactured article, within the meaning of that term
as used in the tariff laws. Washing and scouring wool does not make
the resulting wool a manufacture of wool. Cleaning and ginning
cotton does not make the resulting cotton a manufacture of
cotton."
And in
Anheuser-Busch Brewing Assn. v. United States,
207 U. S. 556,
207 U. S. 562,
where it was claimed that corks for bottles which had undergone
special treatment after importation thereby became articles
manufactured in the United States, this Court said:
"Manufacture implies a change, but every change is not
manufacture, and yet every change in an article is the result of
treatment, labor, and manipulation. But something more is
necessary, as set forth and illustrated in
Hartranft v.
Wiegmann, 121 U.S.
Page 283 U. S. 13
609. There must be transformation; a new and different article
must emerge 'having a distinctive name, character, or use.'"
If it be assumed that the process claims under consideration
cover an invention, we think this lacked novelty when application
was made for the patent August 13, 1923. The underlying conception
had been adequately revealed in Bishop's patent of 1901.
He claimed:
"1. The method of treating articles of food to preserve and
enhance their value, which consists in washing them with a solution
of boracic acid and then applying a coating of gelatin,
substantially as described."
"2. The method of treating articles of food to preserve and
enhance their value, which consists in washing them with a solution
of boracic aid and then applying a coating of gelatin, and finally
wrapping the article in tissue paper which has been impregnated
with a solution of boracic acid, substantially as specified."
And, in the specification, he affirmed:
"This invention aims to prolong the period of usefulness of
fruit, vegetables, eggs, and the like as articles of food and
prevent their usual rapid decay and deterioration, thereby
benefiting the grower, the shipper, the merchant, and the
consumer."
"The invention consists in subjecting the article of food to an
antiseptic bath of purify, cleanse, and kill all germs, then
treating it to a coat of air-excluding material. This process not
only preserves the articles of food, but enhances its value. . .
."
"The application of boracic acid is advantageous in that it
prevents decay and adds to the appearance of the article and is
perfectly harmless to the human system. The gelatin, besides
excluding the air, also adds to the appearance of the article. . .
. "
Page 283 U. S. 14
That boracic (boric) acid -- a weak acid -- and borax, with an
alkaline reaction, inhibit the rapid development of blue mold has
long been known. Both are compounds of boron, and contain the
"boric acid radical." Their antiseptic quality is due to the
presence of that element. For present purposes, the two must be
regarded as equivalents, and the mere substitution of one for the
other would not involve invention or avoid infringement. Walker on
Patents, 6th ed., § 426.
Read together, the claims and specification of the Bishop patent
show that he intended it should have wide application and cover
treatment of citrus, as well as other, fruits. He distinctly states
the application of boracic acid prevents the usual rapid decay, and
upon this basic fact respondent endeavors to support the patent in
suit.
True, Bishop proposed as a secondary step the application of
gelatine which he averred would exclude the air and enhance the
appearance of the article. But Brogden and Trowbridge also said in
their specification that, "if the benefits of the invention are to
be realized to the fullest extent," the fruit after being soaked
should receive an application of protective coating material, such
as paraffin, or like waxy material. If the claims of the patent in
suit are valid, one operating under the process described by Bishop
would infringe -- and, considering the circumstances here
disclosed, that is enough to show invalidity of the later patent.

It lacks novelty. The substance of its disclosures had been
revealed by Bishop twenty years earlier.
